An electrical compass module is gathered the two dimensional surface azimuth information, and is transferred to processing module;

With an electronic pedometer module, the step number that the accumulative total portable terminal moves, and be transferred to processing module.

Further, described processing module is controlled the positional information of memory module storage as the portable terminal of starting point coordinate when gps signal disappears, and sends enabling signal to baroceptor module, electrical compass module and electronic pedometer module.

Further, the described portable terminal data that are transferred to background server comprise starting point coordinate information, pressure information, two dimensional surface azimuth information, mobile step count information and the userspersonal information by the input module input.

Further, described userspersonal information comprises and whenever moves the distance that moves a step or user's age, height, body weight information.

The utility model has the advantages that: this indoor accurate position system, need be at indoor any wireless transmitting device and the framing signal transmitter of setting up in advance, cost is lower, can not only navigate to a certain concrete floor in the indoor environment with a plurality of floors, and can accurately navigate to a certain particular location on this floor, accuracy is higher.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is the communication structure figure of the indoor accurate position system of present embodiment;

Fig. 2 is the workflow diagram of the indoor accurate position system of present embodiment.

Wherein: 1 portable terminal; 10 memory modules; 11 wireless communication modules; 12 display modules; 13 processing modules; 14 input modules; The 15GPS module; 16 baroceptor modules; 17 electrical compass modules; 18 electronic pedometer modules; 2 wireless networks; 3 background servers.

Embodiment

Embodiment: the portable terminal 1 of indoor accurate position system as shown in Figure 1, contain processing module 13 and the memory module 10, wireless communication module 11, display module 12, input module 14, GPS module 15, baroceptor module 16, electrical compass module 17 and the electronic pedometer module 18 that are connected respectively with processing module 13.The memory module 10 of portable terminal 1 is used to store at least one floor maps; Wireless communication module 11 is communicated by letter with background server 3 by wireless network 2; Display module 12 shows current floor maps and shows the particular location of portable terminal on this floor maps in real time; Input module 14 can be used for setting in advance the personal information of mobile phone users, such as the distance of each moved further of user, and perhaps user's age, height, body weight etc.; GPS module 15 is used to receive the GPS framing signal.Baroceptor module 16 is gathered air atmospheric pressure information, and is transferred to processing module 13; Electrical compass module 17 also is digital compass, gathers the two dimensional surface azimuth information, and is transferred to processing module 13; Electronic pedometer module 18 is started working when portable terminal 1 loses gps signal, calculates the step number that portable terminal moves, and is transferred to processing module 13.The work enabling signal of baroceptor module 16, electrical compass module 17, electronic pedometer module 18 is all from processing module 13.

The concrete job step of this indoor accurate position system is as follows:

When portable terminal 1 be in have gps signal local time, GPS module 15 receives gps signal, is positioned by gps signal.When portable terminal 1 is in outdoor inlet chamber, gps signal disappears, carve at this moment, processing module 13 control store modules, 10 storages positional information at this moment is as starting point coordinate, and send enabling signal simultaneously to baroceptor module 16, electrical compass module 17 and electronic pedometer module 18, these three modules are started working.

The 3-4 rice owing to generally be separated by between contiguous floors, the atmospheric pressure of different floors are all different, therefore can determine the floor position at place according to the difference of air pressure.Baroceptor module 16 is measured the pressure information of current location, and the signal of telecommunication is transferred to processing module 13.Present baroceptor module can reach the resolution of 1.5Pa.The angle orientation information of electrical compass module 17 measurement plane two dimensions, electronic compass can reach the angular resolution of 1 degree at present.

Processing module 13 will together radio to background server 3 by wireless communication module 11 from the predefined personal information of user of input module input, real-time step number, starting point coordinate information, real-time pressure information and the two dimensional surface azimuth information that begins to move from starting point coordinate.

Background server 3 comprises information bank, by consulting the pressure information in the information bank, judges the floor at portable terminal 1 place, and floor information is radioed to portable terminal 1.If stored the map of this floor on the portable terminal, then directly shown at display module.If do not store this floor maps on the portable terminal, portable terminal sends transmission command to background server, give portable terminal by background server with this floor maps transfer of data, under the control of processing module 13, map is stored in memory module 10, and be shown to the user by display module 12.

Background server 3 can be determined the particular location of portable terminal on this floor maps by the predefined personal information of user, mobile step number, starting point coordinate information and two dimensional surface azimuth information.The predefined personal information of user can be the distance of each moved further of directly setting, also can be information such as age of individual subscriber, height, body weight, according to these parameters, the Query Information storehouse draws the range information of each moved further of general user by background server.Background server 3 also sends to portable terminal with the positional information that calculates, and by display module 12 current location that demonstration in real time is used on floor maps, thereby the user can see portable terminal floor maps of living in and the exact position on floor maps up till now.

The above only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented with this, and all simple conversion of doing according to the utility model claim and description all should still belong to protection range of the present utility model.
